b05ddad009 gpio updates for v6.7-rc1
GPIOLIB core:
 - provide interfaces allowing users to retrieve, manage and query the
   reference counted GPIO device instead of accessing the private gpio_chip
   structure
 - replace gpiochip_find() with gpio_device_find()
 - remove unused acpi_get_and_request_gpiod()
 - improve the ignore_interrupt functionality in GPIO ACPI
 - correct notifier return codes in gpiolib-of
 - unexport gpiod_set_transitory() as it's unused outside of core GPIO code
 - while there are still external users accessing struct gpio_chip, let's
   make gpiochip_get_desc() public so that they at least use the preferred
   helper
 - improve locking for lookup tables
 - annotate struct linereq with __counted_by
 - improve GPIOLIB docs
 - add an OF quirk for LED trigger sources
 
 Driver improvements:

Merge tag 'gpio-updates-for-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We don't have any new drivers. The loongson driver is getting extended
  with support for new models. There's a big refactor of gpio-pca953x
  and many small improvements to others.

  The GPIO code in the kernel has acquired a lot of cruft over the years
  as well as many abusers of the API across the kernel tree. This
  release cycle we have started a major cleanup and improvement effort
  that will most likely span several releases. We have started by
  converting external users of struct gpio_chip to accessing the wrapper
  around it - struct gpio_device. This is because the latter is
  reference counted while the former is removed when the provider is
  unbound. We also removed several instances of drivers accessing
  private GPIOLIB structures and including the private header from
  drivers/gpio/.

  To that end you'll see several commits aimed at different subsystems
  (acked by relevant maintainers) as well as two merges from the
  x86/platform tree.

  We'll then rework the locking in GPIOLIB which currently uses a big
  spinlock for many different things and could use becoming more
  fine-grained, especially as it doesn't even get the locking right.
  We'll also use SRCU for protecting the gpio_chip pointer against
  in-kernel hot-unplug crashes similar to what we saw triggered from
  user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
  is still vulnerable to these use-cases. I'm just mentioning the plans
  here, this is not part of this PR.

  You'll see some new instances of using __free(). We've added a
  gpio_device_put cleanup helper similar to the put_device one
  introduced by Peter Zijlstra and used it according to the preferred
  pattern except where it didn't make sense.

  GPIOLIB core:
   - provide interfaces allowing users to retrieve, manage and query the
     reference counted GPIO device instead of accessing the private

Merge patch series "RISC-V: ACPI improvements"
Sunil V L <sunilvl@ventanamicro.com> says:

This series is a set of patches which were originally part of RFC v1 series
[1] to add ACPI support in RISC-V interrupt controllers. Since these
patches are independent of the interrupt controllers, creating this new
series which helps to merge instead of waiting for big series.

This set of patches primarily adds support below ECR [2] which is approved
by the ASWG and adds below features.

- Get CBO block sizes from RHCT on ACPI based systems.

Additionally, the series contains a patch to improve acpi_os_ioremap().

RISC-V: clarify the QEMU workaround in ISA parser
Extensions prefixed with "Su" won't corrupt the workaround in many
cases.  The only exception is when the first multi-letter extension in the
ISA string begins with "Su" and is not prefixed with an underscore.

For instance, following ISA string can confuse this QEMU workaround.

*   "rv64imacsuclic" (RV64I + M + A + C + "Suclic")

However, this case is very unlikely because extensions prefixed by either
"Z", "Sm" or "Ss" will most likely precede first.

For instance, the "Suclic" extension (draft as of now) will be placed after
related "Smclic" and "Ssclic" extensions.  It's also highly likely that
other unprivileged extensions like "Zba" will precede.

It's also possible to suppress the issue in the QEMU workaround with an
underscore.  Following ISA string won't confuse the QEMU workaround.

*   "rv64imac_suclic" (RV64I + M + A + C + delimited "Suclic")

This fix is to tell kernel developers the nature of this workaround
precisely.  There are some "Su*" extensions to be ratified but don't worry
about this workaround too much.

This commit comes with other minor editorial fixes (for minor wording and
spacing issues, without changing the meaning).

riscv: correct pt_level name via pgtable_l5/4_enabled
The pt_level uses CONFIG_PGTABLE_LEVELS to display page table names.
But if page mode is downgraded from kernel cmdline or restricted by
the hardware in 64BIT, it will give a wrong name.

Like, using no4lvl for sv39, ptdump named the 1G-mapping as "PUD"
that should be "PGD":

0xffffffd840000000-0xffffffd900000000    0x00000000c0000000         3G PUD     D A G . . W R V

So select "P4D/PUD" or "PGD" via pgtable_l5/4_enabled to correct it.

Merge patch series "riscv: kexec: cleanup and fixups"
Song Shuai <songshuaishuai@tinylab.org> says:

This series contains a cleanup for riscv_kexec_relocate() and two fixups
for KEXEC_FILE and had passed the basic kexec test in my 64bit Qemu-virt.

You can use this kexec-tools[3] to test the kexec-file-syscall and these patches.

riscv: kexec: Cleanup riscv_kexec_relocate (patch1)
==================================================

For readability and simplicity, cleanup the riscv_kexec_relocate code:

 - Re-sort the first 4 `mv` instructions against `riscv_kexec_method()`
 - Eliminate registers for debugging (s9,s10,s11) and storing const-value (s5,s6)
 - Replace `jalr` with `jr` for no-link jump

riscv: kexec: Align the kexeced kernel entry (patch2)
==================================================

The current riscv boot protocol requires 2MB alignment for RV64
and 4MB alignment for RV32.

In KEXEC_FILE path, the elf_find_pbase() function should align
the kexeced kernel entry according to the requirement, otherwise
the kexeced kernel would silently BUG at the setup_vm().

riscv: kexec: Remove -fPIE for PURGATORY_CFLAGS (patch3)
==================================================

With CONFIG_RELOCATABLE enabled, KBUILD_CFLAGS had a -fPIE option
and then the purgatory/string.o was built to reference _ctype symbol
via R_RISCV_GOT_HI20 relocations which can't be handled by purgatory.

As a consequence, the kernel failed kexec_load_file() with:

[  880.386562] kexec_image: The entry point of kernel at 0x80200000
[  880.388650] kexec_image: Unknown rela relocation: 20
[  880.389173] kexec_image: Error loading purgatory ret=-8

So remove the -fPIE option for PURGATORY_CFLAGS to generate
R_RISCV_PCREL_HI20 relocations type making puragtory work as it was.

  rework, modify the thermal governor interface so as to use trip
  pointers for representing trip points in it, switch over multiple
  thermal drivers to using void platform driver remove callbacks, add
  support for 2 hardware features to the Intel int340x thermal driver,
  add support for new hardware on ARM platforms, update documentation,
  fix problems, clean up code and update the MAINTAINERS record for
  thermal control.

91562895f8 ext4: properly sync file size update after O_SYNC direct IO
Gao Xiang has reported that on ext4 O_SYNC direct IO does not properly
sync file size update and thus if we crash at unfortunate moment, the
file can have smaller size although O_SYNC IO has reported successful
completion. The problem happens because update of on-disk inode size is
handled in ext4_dio_write_iter() *after* iomap_dio_rw() (and thus
dio_complete() in particular) has returned and generic_file_sync() gets
called by dio_complete(). Fix the problem by handling on-disk inode size
update directly in our ->end_io completion handler.

ce56d21355 ext4: fix racy may inline data check in dio write
syzbot reports that the following warning from ext4_iomap_begin()
triggers as of the commit referenced below:

        if (WARN_ON_ONCE(ext4_has_inline_data(inode)))
                return -ERANGE;

This occurs during a dio write, which is never expected to encounter
an inode with inline data. To enforce this behavior,
ext4_dio_write_iter() checks the current inline state of the inode
and clears the MAY_INLINE_DATA state flag to either fall back to
buffered writes, or enforce that any other writers in progress on
the inode are not allowed to create inline data.

The problem is that the check for existing inline data and the state
flag can span a lock cycle. For example, if the ilock is originally
locked shared and subsequently upgraded to exclusive, another writer
may have reacquired the lock and created inline data before the dio
write task acquires the lock and proceeds.

The commit referenced below loosens the lock requirements to allow
some forms of unaligned dio writes to occur under shared lock, but
AFAICT the inline data check was technically already racy for any
dio write that would have involved a lock cycle. Regardless, lift
clearing of the state bit to the same lock critical section that
checks for preexisting inline data on the inode to close the race.

853eebe6ec drm/amdgpu: add unmap latency when gfx11 set kiq resources
[why]
If driver does not set unmap latency for KIQ, the default value of KIQ
unmap latency is zero. When do unmap queue, KIQ will return that almost
immediately after receiving unmap command. So, the queue status will be
saved to MQD incorrectly or lost in some chance.

[how]
Set unmap latency when do kiq set resources. The unmap latency is set to
be 1 second that is synchronized with Windows driver.

9793c269da dm crypt: account large pages in cc->n_allocated_pages
The commit 5054e778fc ("dm crypt: allocate compound pages if
possible") changed dm-crypt to use compound pages to improve
performance. Unfortunately, there was an oversight: the allocation of
compound pages was not accounted at all. Normal pages are accounted in
a percpu counter cc->n_allocated_pages and dm-crypt is limited to
allocate at most 2% of memory. Because compound pages were not
accounted at all, dm-crypt could allocate memory over the 2% limit.

Fix this by adding the accounting of compound pages, so that memory
consumption of dm-crypt is properly limited.

Simplify symlink_hash() by using crypto_shash_digest() instead of an
init+update+final sequence.  This should also improve performance.

d328c09ee9 smb: client: fix use-after-free bug in cifs_debug_data_proc_show()
Skip SMB sessions that are being teared down
(e.g. @ses->ses_status == SES_EXITING) in cifs_debug_data_proc_show()
to avoid use-after-free in @ses.

This fixes the following GPF when reading from /proc/fs/cifs/DebugData
while mounting and umounting
